public fun bitwise_not(x: u256): u256
Implementation
public fun bitwise_not(x: u256): u256 {

}

Function max​

Return the larger of x and y

public fun max(x: u256, y: u256): u256
Implementation
public fun max(x: u256, y: u256): u256 {
std::macros::num_max!(x, y)
}

Function min​

Return the smaller of x and y

public fun min(x: u256, y: u256): u256
Implementation
